If 10 million Muslims want to go to Michigan and live under sharia law there on their own property, why should I stop them?
You probably shouldn't but the country should. If Europe is any example limiting Muslim immigration is in our best interests. I fully expect in the next 25 years civil wars to break out in Europe as the Muslim population grows and clashes with the natives. I don't think the two cultures are compatible. After 9/11 Ron Paul suggested we end immigration from nations where terrorists come from. It doesn't take a rocket scientist to figure out he was talking about Muslim nations.
